Death Record Look-Up Please...

I am searching for Death Record(s), that I am hoping may be found in Pickaway County; either at the Court House, or possibly the Genealogy Society. I am looking for a record of death or burial, for Eliza Lisa Turner. Eliza was born 1855 to the parents of James Turner & Mary DeLong. According to the 1880 census, both James and Eliza were both still living. The 1900 Federal Census shows that James is deceased,& Eliza is no longer listed; so I presume that Eliza is now also deceased. According to Mary DeLong-Turner's Death Certificate from 1909, it shows that at the time of her death, she still had 8 living children out of 10. I can account for all of the living children, but can find NOTHING for Eliza after 1880. These Turners made their home in Perry Twp., Hocking, Ohio. Mary, and some of her children's funerals were held by Defenbaugh Funeral Home in Tarlton, Ohio, and because of the age of the records, the funeral home no longer has them. I am hoping that maybe Eliza & James funeral were also held by Defenbaugh Funeral Home. James Turner was born 1820 in Ohio, some records show 1824; no parents for James can be found. I would guess that Eliza died sometime between 1880-1900. Any attempts to find these death records, would be greatly appreciated. I have looked for this information since 1990, and admit; starting to lose faith! Thank you.
